Question

What are the 3 types of elasticity?

Answer 1

The three 3 types of elasticity:

1. Young's modulus of elasticity: Within the elastic limit, the ratio of longitudinal stress and longitudinal strain is called Young’s modulus of elasticity.
   $\mathrm{Young}\text{'}\mathrm{s}\mathrm{modulus}=\frac{\mathrm{Longitudinal}\mathrm{stress}}{\mathrm{Longitudinal}\mathrm{strain}}$
2. Bulk modulus: Within the elastic limit, the ratio of the volume stress and the volume strain is called the bulk modulus of elasticity.
   $\mathrm{Bulk}\mathrm{modulus}=\frac{\mathrm{Volume}\mathrm{stress}}{\mathrm{Volume}\mathrm{strain}}$
3. Rigidity modulus: The ratio of shearing stress to shearing strain is called rigidity modulus.
   $\mathrm{Rigidity}\mathrm{modulus}=\frac{\mathrm{shearing}\mathrm{stress}}{\mathrm{shearing}\mathrm{strain}}$
